Dorn offers two suggestions: (1) Conducting external reviews of assistant-professor candidate pools, modeled on the procedures used when candidates go up for tenure, in which outside reviewers would take a look at the qualifications of the final pool, those who just missed the cut, and a random sampling of the rest of the applicants: and (2) using target of opportunity lines to promote pedagogical diversity as well as the more traditional types of diversity for which TOA lines currently are used.
Both seem to me to be great ideas. They share a common element: administrative willingness to proactively promote intellectual diversity and to devote financial resources to the cause, recognizing that faculty self-governance and a prudent system of checks and balances need not be irreconcilable. To my knowledge, there isn't one institution in the country that gives departments the sole power to make tenure decisions--there's a recognition that some internal check needs to exist. The same principle should apply to the hiring process. Without some outside pressure from campus administrations, there's no reason to believe that intellectually uniform departments will suddenly decide to change their ways.
